SPRING ROLLER FOR SUN VISORS.

Application led .Tune 19, 1922.

To all whom 'it may concern.'

Ile it known that I. Arnulf'. il. Lewis, a citizen of' the United States, residing at lv'lansfield, in the county of Richland and State of Ohio, have invented a new and useful Spring Roller for Sun Visors, of which the following is a s} ecilication.

This invention aims to provide a novel form of spring-actuated curtain roller, adapted to be used, primarily but not exclusively, to operate a curtain on an automobile, for the purpose of shielding the eyes of the driver from the light.

In the drawings Figure 1 shows in elevation, a shade roller constructed in accordance with the invention; Figure Q is a longitudinal section of the roller; Figure 3 is an elevation showing one cap and the head on the end of the shaft; Figure -fl is a cross section on the line L1 1 of Figure 2* Figure 5 is a. transverse section showing the casing, the spring anchor and the curtain.

In carrying out the invention, there is provided a tubular casing 1 preferably made of metal, and forming part of the shade roller, the casing having a longitudinal slot 2 and including an end wall 3 carrying a trunnion 41. A cup-shaped cap 5 is mounted on one end of the casing 1, the trunnion 4 extending through the cap, and the cap being held in place by a securing element 6. Circuin ferentially spaced seats 7 are fashioned in the cap 5. The roller embodies a spring anchor and bearing 8 of' U-shape, the meinber 8 comprising an end plate 9 and arms 10 projecting therefrom, the arms having eX- tensions 11 which are trough-shaped in cross section, to fit closely within the casing 1, the longitudinal edges of the extensions 11 being spaced as indicated at 12, securing elements 14 connecting the member 8 to the casing 1 for rotation therewith. A washer 15 abuts against the end of the casing 1 and against the ends of the extensions 11 of the member 8, and has an outwardly extended annular flange 16.

A. shaft 17 is located within the member 8 and carries a head 18 disposed Within the flange 16 of the washer 15, the head having a hub 19 provided with an opening 20 wherein the shaft 17 is mounted, the hub having openings adapted to receive securing ele- Serial No. 569,227.

ments 22, the outer ends of which forni fingers A helical spring 241 is disposed within the member 8 and is secured by the elements 22 to the head 18 on the shaft 17. the inner end of the spring 211 being secured at to the member 8, at a point adjacent to the end plate 9, the shaft 17 being ei:- tended through the end plate 9 to aid in supporting the roller for rotation. A cap 26 surrounds the casing 1 and aids in holding the securing elements 14 in place. The cap 26 has an inwardly extended flange 27 which overlaps the outer surface of the head 18 on the shaft 17. The numeral 28 marks a flexible curtain having a socket 29 wherein a retaining rod 30 is mounted. The curtain 28 extends through the slot 2 of the roller casing 1, the socket 29 of the curtain being engaged in one of the spaces 12 of the member Assuming that the trunnion 1l: is journaled in one bracket (not shown) and that the fingers Q3 are received in another bracket (not shown), it will be obvious that when the curtain Q8 is unrolled, the spring 24. will be tensioned, the spring reacting to wind up the curtain.

I claim In a device of the class described, a tubular casing having a. longitudinal slot, a combined spring-anchor and bearing, of U- shape, located within the casing and including an end plate and arms projecting from the end plate, the arms having troughshaped extensionsfitting closely in the casing and spaced to register with the slot, for the reception of a curtain, a securing element connecting one extension with the casing, a cap about the casing and retaining the securing' element, a cap having an inwardly extended flange, a shaft journaled in the end plate and having an enlarged head journaled between the end of the cias ing and the flange, and a` spring disposed about the shaft and loca-ted within the anchor, one end of the spring being connected to the head, and the other end of the spring being connected to one arm of the anchor.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
